DOOR-#HANGER SPECIFICATION forming part of Letters Patent No. 438,111, dated October 7, 1890.

Application iiled January 29, 1890. Serial No. 338,491. (No model.)

To all whom, it may concern.-

Beit known that LWILLIAM LUITNK, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and usefulA Improvements in Door-Hangers; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to door-hangers; and it consists in certain peculiarities of construc- Io tion and combination of parts to be hereinafter described with reference to the accompanying drawings and subsequently claimed.

In the drawings, Figure l represents a side elevation, partly in section, and illustrates the construction and relative arrangement of parts constituting my invention; and Fig. 2, a vertical transverse section on an imaginary line passing through the door-casing and a rider-bar of one of the door-hangers. Figs. 3

2o and 4 are exaggerated diagrams designed to illustrate the working of my invention.

Referring by letter and ligure to the drawings, A represents a door, and secured to the upper edge thereof, by means of screws Z) or other suitable means, is a plate B, having offset ends c, the latter being provided with openings through which are passed the screwthreaded right-angle ends CZ of rider-bars C, said ends of the rider-bars being engaged by 3o nuts D arranged to bear against the under faces of the offset portions of said plates. The rider-bars O rest on axles E of flanged rollers F, and these rollers revolve on tracks G, se-

cured upon the interior of the door-casing, as

3 5 is usual in the art to which my invention relates, and it is to be understood that the success of my invention depends on the employment of two hangers in connection with each door, and that each roller is free to travel 4o back and forth the entire length of its relative hanger, as will be hereinafter more fully described.

In the diagram views, Figs. 3 and 4, the right-angled ends of the rider-bars are num bered l, 2, 3, and 4, and in describing the operation and advantages of my invention said ends of the rider-bars will be hereinafter designated by their respective numbers.

The door and its two rider-bars (shown in 5o Figs. 3 and 4) are proportionate to each other,

and it is to be understood that the Weight of said door keeps the rider-bars always against the 'axles of the rollers, and While these rollers are rotating on the tracks the rotation of said axles against said rider-bars is in a reverse direction. Now we will assume that a building has settled in such a manner that a door drawn out of its pocket stands in the position shown in full lines, Fig. 3, the line 5 in the same figure representing an opposing jamb 6o of the door-casing, or the edge of another door, also drawn out of its pocket to meet the first door at the center of the casing. In this position of the first door the axles of the rollers are against the inner ends 2 and 4 of the 65 respective rider-bars and the door stands open at the top, or, in other words, its outer edge will not meet flush with the opposing surface.

To remedy this defectithe nut on the end 2 of one rider-bar is run down and the nut on 7o the end 4 of the other rider-bar is run up, and thus said door is made to stand in the position shown by dotted lines in said Fig. 3, when the axles of the rollers are against said ends 2 4 of the respective rider-bars, said door being then drawn out or in its closed position. Should the house have settled in such a manner that the angle of line 5 would be reverse to that shown, the adjustment of the door to compensate for the settling would be reverse 8 5 to that above described, or, in other Words, the nut on the end 2 of one rider-bar would be run up and the nut on the end 4 of the other rider-bar Would be run down to bring the outer edge of said door parallel to the sur- 8 5 face opposed to said outer edge when the axles of the rollers arrived at said ends 2 and 4 of the respective rider-bars. Having adjusted the doorso that it will close evenly when out of the pocket, We will assume that when 9o said door is pushed back into said pocket it will stand in the position shown by full lines, Fig. 4, thereby projecting somewhat beyond the jamb of the casing, the line 6 in Figs. 3 and 4 being employed to represent said jamb. 95 Vhen the door is in the position last described, the axles of the rollers stand against the ends l 3 of the respective riderbars, and

to bring the outer edge of said door Hush with the jamb I run upthe nut on the end l of one roo rider-bar and run down the nut on the end 3 of the other rider-bar. This operation brings the door into the position shown by dotted lines, Fig. 4, and thus compensates for the settling of the building. Should the settling be in reverse to what is shown by line 6, the adjustment of said nuts would be reverse to that described. The door is now adjusted so as to close evenly when out of the pocket, and to come flush with the j amb when in said pocket, the proper cant of said door in either direction being automatically effected by the travel of the rider-bars and the rotation of the roller-axles against said rider-bars in a direction reverse to said travel.

By the above description it will be seen that the outer or odd-numbered ends of both riderbars are relative as regards adjustment, and the inner. or even-numbered ends of said rider-bars have a like relation, whereby I obtain two adjustments of a single door without losing either of said adjustments, this being a feature of material advantage, especially as it requires no special tools or appliances other than an ordinary wrench to adjust the riderbars, while at the same time the operation can be performed by any person in a very short time without damage to the building in which said door may be hung.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is`

The combination, with a door, track, and two rollers mounted on the track, of a riderbar loose from end to end on the axle of each roller, and havingboth ends vertically adjustable on the door, the corresponding ends (inner and outer) of both rider-bars being relative as regards an adjustment, whereby two adjustments of said door may be effected without the loss of either, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wisconsin, in the presence, of two witnesses.
